SPECIFICATION forming part of Letters Patent No. 598,133, dated February 1, 1898.

Application filed February 8, 18 9 7.

To a/ZZ whom zit may concern:

Be it known that l, Looms H. Bumm/IAN, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings, in the State of New York, have invented certain new and useful Improvements in Ball- Cocks, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to valves such as are commonly employed for the purpose of controlling the delivery of water to a flushing tank or lreservoir and which operate in such a manner as to permit the further inflow of water when the supply in the tank or reservoir is drawn oft' and to check the further indow when the water has risen again in the tank or reservoir to a predetermined height. Such valves are commonly operated by a lever having at its free end a float which rises and falls with the water in the tank. It has been usual to vary the size of the float according to the pressure of the Water in the supply-pipes, a large iloat' being necessary when the pressure of the water is great in order to keep the valve closed when the tank is full. Hollow metal balls are usually emcost of making them increase rapidly with an increase in size, but the large balls are cumbersome and take up too much room. It has been sought to obviate the necessity of using large iioats by employing some form of balance-valve, but such valves are expensive to manufacture and are somewhat liable to leak and get out of order.

With all of the diiculties above mentioned in mind I have sought to produce a valve which can be operated by a small float and when closed will be positively locked against the pressure of the water, so that it shall not be necessary to increase the size of the float, no matterhow great the pressure of the water in the supplypipe may be.

A convenient and desirable construction in which my invention maybe embodied is illusstrated in vthe accompanying drawings, in which- Figure l is a sidel elevation of a valve and doat applied to a tank, a portion of the latter being shown in section. Fig. 2 is a lon- Seria-l No. 622,441.0. (No model.)

gitudinal central section of the improved valve. Fig. 3 is afront elevation of the upper' portion thereof. Fig. 4 is a transverse section on the plane indicated by the line a: of Fig.A 2.

The valve shown in the drawings comprises a tubular body portion a., having a flange a'. and adapted to be secured in the bottom or side wall of the tank A by a nnt b in the usual and well-known manner. It is also adapted to be connected to the supply-pipe c'by a Sleeve-nut c in the usual manner. ln the end of the tubular body ce is a port cl2 for the admission of water, formed at its inner end with a suitable shoulder or valve-seat co3. The valve-plugd enters loosely within the body a., and is preferably provided at its lower end with a washer d to make a tight joint with the valve-seat a3 when the plug is held down. The plug d is suitably shaped in crosssec tion, as represented, for example, in Fig. 1i, to permit the water which ent-ers through the port a2 to pass freely between the plug d and the -tubular body portion u into the tank o1' reservoir A.

From the upper end of the body portion u rise two posts or standards a4 to support a pivot-rod e, upon which is mounted the lever f, which controls the Valve. One arm of the lever is extended, as at f", to receive the ball or float t, which rises and falls with the water in the tank and effects the movements of the lever. The other arm f2 of the lever f is extended toward the valve-plug d, making an elbow-lever. To the extremity of the arm f2 is connected a link h, which bears upon the plug d, the latter preferably having a recess d2 to receive the end oi the link. If desired, the link may be made in two parts in order to be extensible for purposes of adjustment, the part h being threaded into the main part of the link and iixed in position by a locknut 71.2. A projection f3 is formed on the arm j2 to bear upon one of the standards a4 and thereby prevent movement of the lever beyond the position indicated in Fig. 2, in which the center of the connection between the link h and the arm f2 is but slightly beyond a straight line between the center of the pivot e and the center of the bearing of the link 71, upon the plug d. vIt will be seen that the lever f and IOO Y IO
